  • Publication number: 20170218819
    Abstract: A reductant supply system includes a pump having a suction side and a discharge side, and a tank that holds a reductant therein. A reductant supply passageway extends from the tank to the suction side of the pump so as to supply the reductant from the tank to the pump. Further, a reductant discharge passageway extends from the discharge side of the pump and is configured to supply the reductant to a reductant injection assembly that injects the reductant into an exhaust stream of an engine. The system further includes purge componentry that connects the reductant supply passageway to an ambient air source during a purging operation such that the reductant supply system draws air from the air source sequentially through the purge passageway, the reductant supply passageway, and the pump assembly to purge at least the reductant supply passageway and the pump assembly during the purging operation.

  • Patent number: 9670818
    Abstract: A reductant dosing system is disclosed as having a pump, and suction, discharge, and return passages. The system may also have a return valve, an air passage, and an air valve. The system may additionally have an air passage pressure sensor, a discharge passage pressure sensor, and a controller. The controller may be configured to calculate a first average pressure inside the discharge passage while the pump is off, the air valve is open, and the return valve is closed; and calculate a second average pressure inside the discharge passage while the pump is off, the air valve is open, and the return valve is open. The controller may also be configured to determine a pressure drop inside the discharge passage based on the first and second average pressures, and to determine that priming is successful based on the pressure drop and pressures of the discharge and air passages.

  • Patent number: 9217353
    Abstract: A mixer is disclosed for use in a fluid injection system. The mixer may have an impingement floor oriented generally perpendicular to an intended fluid injection direction and generally parallel with a flow direction. The mixer may also have a first side wall connected along a lengthwise edge of the impingement floor and generally parallel with the flow direction, and a second side wall connected along an opposing lengthwise edge of the impingement floor and generally parallel with the flow direction. The mixer may further have at least one shelf extending between the first and second side walls and generally parallel with the flow direction. The at least one shelf may have a plurality of vanes protruding toward and away from the impingement floor that promotes mixing of an injected fluid.
